Scavenging reaction
WebThe intensities were extrapolated to zero time to estimate the quantity of DMPO-OH formed during gamma-irradiation. By using these values, the reaction rate constant between OH radical and EGCg was calculated as a ratio to that of DMPO. It was shown that this method is useful for comparing the OH radical-scavenging activity of various antioxidants. WebMar 21, 2024 · Conclusions. We have studied the reaction of H 2 S with TZ and oxazolidine to elucidate, explain, or confirm different aspects related to their proposed reaction …

WebFree radical scavenging reactions of sesamol, 5-hydroxy-1,3-benzodioxole, have been studied using a nanosecond pulse radiolysis technique. Sesamol efficiently scavenges hydroxyl, one-electron oxidizing, organo-haloperoxyl, lipid peroxyl, and tryptophanyl radicals. Its antioxidant activity has also been evaluated with cyclic voltammetry. WebSuperoxide scavenging activity increases proportionally with the degree of chiral inversion. Characterization of the NCC sequence within longer peptides with absorption, circular dichroism (CD), and magnetic CD (MCD) spectroscopies and mass spectrometry (MS) shows that the geometry of metal coordination is maintained, though the electronic …
